The lush PHS Pop-Up Garden on South Street in Graduate Hospital is still packing in lovers of alfresco good times nightly.

Though just reveling in sunshine or moonlight in the garden is enjoyable, tonight the pop-up hosts a free outdoor movie screening with movie-themed quizzo.

Once the sun sets tonight, The Great Outdoors, an ’80s comedy starring Dan Aykroyd and John Candy, fills the alfresco movie screen. Prior to the screening, hang at the beer garden for a few rounds of The Great Outdoors-themed quizzo, which will begin at 6 p.m.

Make it a complete movie night with food and refreshments from the bar, Jamaican Jerk Hut or an on-site food truck — tonight’s featured food truck will be Oink and Moo.

Plus, guests who make a donation to PHS City Harvest will receive a free bag of popcorn.
